Description
Die vorliegende Erfindung betrifft ein wasserführendes Haushaltsgerät mit einem Aufnahmebereich und einer Anordnung zur akustischen und thermischen Isolation des Aufnahmebereichs des wasserführenden Haushaltsgeräts. Das wasserführende Haushaltsgerät ist insbesondere eine Geschirrspülmaschine. Der Aufnahmebereich ist insbesondere ein Spülbehälter der Geschirrspülmaschine.
Zur akustischen Isolation eines Spülbehälters einer Geschirrspülmaschine ist es bekannt, auf den Spülbehälter Bitumenmatten aufzubringen. Die Bitumenmatten können beispielsweise mit Hilfe eines Schmelzklebers außenseitig auf den Spülbehälter aufgeklebt werden. Derartige Bitumenmatten haben ein hohes Wärmeaufnahmevermögen und leiten die aufgenommene Wärme von dem Spülbehälter weg. Wird der Anteil der mit den Bitumenmatten belegten Fläche des Spülbehälters reduziert, lässt sich die Energieaufnahme der Geschirrspülmaschine reduzieren. Diese Reduktion der belegten Fläche hat jedoch zur Folge, dass die Schallemission der Geschirrspülmaschine ansteigt.

For the acoustic insulation of a washing container of a dishwasher, it is known to apply bitumen mats to the washing container. The bitumen mats can be glued to the outside of the washing container, for example with the aid of a hot melt adhesive. Such bitumen mats have a high heat capacity and direct the heat absorbed by the washing away. If the proportion of the surface occupied by the bitumen mats of the washing container is reduced, the energy consumption of the dishwasher can be reduced. However, this reduction of the occupied area has the consequence that the noise emission of the dishwasher increases.

Vor diesem Hintergrund besteht eine Aufgabe der vorliegenden Erfindung darin, ein wasserführendes Haushaltsgerät mit einem Aufnahmebereich und einer verbesserten Anordnung zur akustischen und thermischen Isolation des Aufnahmebereichs des wasserführenden Haushaltsgeräts zur Verfügung zu stellen.Against this background, an object of the present invention is to provide a water-conducting household appliance with a receiving area and an improved Arrangement for acoustic and thermal insulation of the receiving area of the water-bearing household appliance to provide.
Demgemäß wird ein wasserführendes Haushaltsgerät mit einem Aufnahmebereich und einer Anordnung zur akustischen und thermischen Isolation des Aufnahmebereichs des wasserführenden Haushaltsgeräts, insbesondere eines Spülbehälters einer Geschirrspülmaschine, vorgeschlagen. Die Anordnung umfasst ein erstes Isolationselement, welches dazu eingerichtet ist, den Aufnahmebereich thermisch zu isolieren, und ein zweites Isolationselement, welches dazu eingerichtet ist, den Aufnahmebereich akustisch zu isolieren, wobei das erste Isolationselement zwischen dem Aufnahmebereich und dem zweiten Isolationselement angeordnet ist und wobei das erste Isolationselement direkt an den Aufnahmebereich angeschäumt ist. Das erste Isolationselement weist sowohl eine spezifische Wärmeleitfähigkeit von kleiner als 0,1 W/(m*K), bevorzugt von kleiner als 0,05 W/(m*K), als auch eine Massendichte oder Dichte zwischen 5 und 90 kg/m3 auf.Accordingly, a water-conducting household appliance having a receiving area and an arrangement for acoustic and thermal insulation of the receiving area of the water-conducting household appliance, in particular a washing container of a dishwasher, proposed. The assembly includes a first insulation member configured to thermally insulate the receiving area and a second insulation member configured to acoustically isolate the receiving area, wherein the first insulation member is disposed between the receiving area and the second insulation member, and wherein first insulation element is foamed directly to the receiving area. The first insulation element has both a specific thermal conductivity of less than 0.1 W / (m * K), preferably less than 0.05 W / (m * K), as well as a mass density or density between 5 and 90 kg / m 3 on.
Dadurch, dass das erste Isolationselement direkt an den Aufnahmebereich angeschäumt ist, kann auf ein nachträgliches Anbringen der Anordnung an den Aufnahmebereich verzichtet werden. Hierdurch ist eine Kostenreduktion bei der Herstellung eines wasserführenden Haushaltsgeräts mit einer derartigen Anordnung erzielbar. Weiterhin kann hierdurch die Montagekomplexität reduziert werden, da ein zusätzlicher Arbeitsschritt des Isolierens des Aufnahmebereichs verzichtbar ist.The fact that the first insulating element is foamed directly to the receiving area, can be dispensed with a subsequent attachment of the arrangement to the receiving area. As a result, a cost reduction in the production of a water-conducting household appliance can be achieved with such an arrangement. Furthermore, as a result, the assembly complexity can be reduced, since an additional step of isolating the receiving area is dispensable.
Insbesondere kann die Anordnung während der Herstellung des Aufnahmebereichs an diesem angebracht werden. Der Aufnahmebereich weist vorzugsweise eine Wandung mit zwei einander gegenüberliegenden Seitenwänden, einer Decke, einem der Decke gegenüberliegend angeordneten Boden und eine einer Tür des Aufnahmebereichs gegenüberliegend angeordnete Rückwand auf. Die Anordnung kann an der gesamten Wandung und an der Tür vorgesehen sein. Die Anordnung kann die Wandung oder einen Teil der Wandung umfassen. Alternativ kann die Anordnung beispielsweise nur an den Seitenwänden, an der Rückwand und an der Decke vorgesehen sein. Vorzugsweise wird der Aufnahmebereich völlig mit dem ersten Isolationselement umschäumt. Insbesondere ist die Anordnung außenseitig an dem Aufnahmebereich vorgesehen.In particular, the assembly may be attached thereto during manufacture of the receiving area. The receiving area preferably has a wall with two opposite side walls, a ceiling, a floor arranged opposite the ceiling and a rear wall arranged opposite a door of the receiving area. The arrangement may be provided on the entire wall and on the door. The arrangement may comprise the wall or a part of the wall. Alternatively, the arrangement may be provided, for example, only on the side walls, on the rear wall and on the ceiling. Preferably, the receiving area is completely foamed with the first insulating element. In particular, the arrangement is provided on the outside on the receiving area.
Vorzugsweise ist eine spezifische Wärmekapazität des ersten Isolationselements möglichst gering und kleiner als 1.400 J/(kg*K). Zur Verbesserung der Haftung auf einer Oberfläche des Aufnahmebereichs können dem Material des ersten Isolationselements chemische Zusätze beigemischt sein und/oder die Oberfläche des Aufnahmebereichs kann vorbehandelt, beispielsweise aufgeraut werden, so dass das erste Isolationselement insbesondere unlösbar mit dem Aufnahmebereich verbunden ist. Das erste Isolationselement stellt insbesondere eine steife Verbindung zwischen dem Aufnahmebereich und dem zweiten Isolationselement dar. Das heißt, das erste Isolationselement kann Schwingungen des Aufnahmebereichs, insbesondere verlustfrei oder zumindest verlustarm, auf das zweite Isolationselement übertragen.Preferably, a specific heat capacity of the first insulating member is as small as possible and smaller than 1,400 J / (kg * K). In order to improve the adhesion on a surface of the receiving area, chemical additives may be added to the material of the first insulating element and / or the surface of the receiving area may be pretreated, for example roughened, so that the first insulating element is in particular permanently connected to the receiving area. The first insulation element in particular represents a rigid connection between the receiving region and the second insulation element. That is to say, the first insulation element can transmit vibrations of the reception region, in particular lossless or at least low-loss, to the second insulation element.
Die Massendichte oder Dichte des zweiten Isolationselements ist vorzugsweise größer als 1.000 kg/m3.The mass density or density of the second insulating member is preferably larger than 1,000 kg / m 3 .

Hierdurch wird verhindert, dass das zweite Isolationselement dem Aufnahmebereich Wärme entzieht. Hierdurch wird die Energieeffizienz des wasserführenden Haushaltsgeräts verbessert. Das zweite Isolationselement ist vorzugsweise dazu eingerichtet, Schwingungen in Wärme umzuwandeln.This prevents the second insulating element from extracting heat from the receiving area. As a result, the energy efficiency of the water-conducting household appliance is improved. The second insulation element is preferably configured to convert vibrations into heat.

Vorzugsweise ist die Dicke des ersten Isolationselements kleiner als 50 mm. Die Mindestdicke des ersten Isolationselements beträgt vorzugsweise 5 mm. Vorzugsweise ist eine Dicke des zweiten Isolationselements kleiner als die Dicke des ersten Isolationselements. Insbesondere beträgt die Dicke des ersten Isolationselements ein Vielfaches der Dicke des zweiten Isolationselements. Das zweite Isolationselement kann beispielsweise eine Dicke von 1 bis 5 mm aufweisen.
Gemäß einer weiteren Ausführungsform weist das zweite Isolationselement bei einer Temperatur von 20 °C einen Verlustfaktor von größer als 0,08, bevorzugt von größer als 0,15, auf.
Hierdurch wird eine gute Entdröhnung des Aufnahmebereichs beziehungsweise eine Dämpfung der Schwingungen des Aufnahmebereichs erreicht.Preferably, the first insulating element is made of a closed-cell plastic material. Alternatively, the first insulating element may be made of a polystyrene foam, for example.
According to a further embodiment, the second insulation element is made of a bitumen material, in particular of a metal- and / or rock-filled bitumen material, or of a plastic material, in particular of a metal- and / or rock-filled plastic material.
The bitumen material or the plastic material may comprise finely divided metal powder or rock flour. The second insulating element is preferably plate-shaped or mat-shaped. For example, the second insulation element may also be made of a butyl material. Alternatively, the second insulating element may be a metal plate, in particular a steel plate.
According to a further embodiment, the first insulation element has a thickness of 5 to 50 mm, preferably 10 to 45 mm, more preferably 15 to 40 mm. Preferably, the thickness of the first insulating element is less than 50 mm. The minimum thickness of the first insulating element is preferably 5 mm. Preferably, a thickness of the second insulating member is smaller than the thickness of the first insulating member.

As a result, a good Entdröhnung the receiving area or a damping of the vibrations of the receiving area is achieved.
Gemäß einer weiteren Ausführungsform ist außenseitig an dem zweiten Isolationselement ein Abdeckelement, insbesondere ein Papierbogen, eine Metallfolie oder eine Metallplatte, angeordnet.According to a further embodiment, a cover element, in particular a paper sheet, a metal foil or a metal plate, is arranged on the outside of the second insulation element on the outside.
Vorzugsweise weist das Abdeckelement einen sehr geringen Emissionskoeffizienten auf. Vorzugsweise ist der Emissionskoeffizient des Abdeckelements kleiner als 0,5, bevorzugt kleiner als 0,1. Hierdurch kann der Energieverlust weiter gesenkt werden. Vorzugsweise wird als Material für das Abdeckelement Aluminiumfolie eingesetzt.Preferably, the cover has a very low emission coefficient. Preferably, the emission coefficient of the cover is less than 0.5, preferably less than 0.1. As a result, the energy loss can be further reduced. Preferably, aluminum foil is used as the material for the cover element.
Gemäß einer weiteren Ausführungsform ist zwischen dem ersten Isolationselement und dem zweiten Isolationselement ein Masseelement, insbesondere eine Metallplatte, angeordnet.According to a further embodiment, a mass element, in particular a metal plate, is arranged between the first insulation element and the second insulation element.
Die Metallplatte kann mit dem Abdeckelement abgedeckt sein. Alternativ kann auf das Abdeckelement verzichtet werden. Anstelle eines Stahlblechs kann für das Masseelement auch ein dämpfender Belag mit hoher Massendichte oder Dichte verwendet werden. Die Dichte dieses Materials ist dabei vorzugsweise größer als 1.800 kg/m3, bevorzugt größer als 2.200 kg/m3. Optional kann auch hier ein Abdeckelement mit niedrigem Emissionskoeffizienten vorgesehen sein. Durch diesen Schichtaufbau wird über den gesamten Spülzyklus eine effektiv wirksame thermische Isolation des Aufnahmebereichs des wasserführenden Haushaltsgeräts realisiert.The metal plate may be covered with the cover. Alternatively, can be dispensed with the cover. Instead of a steel sheet may be used for the mass element, a damping coating with high mass density or density. The density of this material is preferably greater than 1,800 kg / m 3 , preferably greater than 2,200 kg / m 3 . Optionally, a cover element with a low emission coefficient can also be provided here. By means of this layer structure, effective thermal insulation of the receiving area of the water-conducting domestic appliance is realized over the entire rinsing cycle.
Gemäß einer weiteren Ausführungsform ist in dem ersten Isolationselement ein Wärmetauscher angeordnet.According to a further embodiment, a heat exchanger is arranged in the first insulation element.
Vorzugsweise ist der Wärmetauscher mit Material des ersten Isolationselements umschäumt. Der Wärmetauscher kann beispielsweise ein Kapillarrohrwärmetauscher, ein Kupferrohrwärmetauscher, ein Plattenwärmetauscher oder dergleichen sein. Vorzugsweise ist der Wärmetauscher mindestens an Seitenwänden, vorzugsweise auch an der Rückwand und optional an der Decke des Aufnahmebereichs angeordnet. Die steife Verbindung zwischen dem Aufnahmebereich und dem zweiten Isolationselement bleibt hierbei erhalten. Hierzu wird der Abstand zwischen Rohren des Wärmetauschers ausreichend groß bemessen. Der Abstand zwischen Außenseiten der Rohre beträgt dabei mindestens den Durchmesser der einzelnen Rohre. Um eine vollständige Entleerung des Wärmetauschers zu ermöglichen, können die Rohre desselben senkrecht oder zumindest schräg mit ausreichendem Gefälle an dem Aufnahmeabschnitt angebracht werden.Preferably, the heat exchanger is foamed with material of the first insulating element. The heat exchanger may be, for example, a capillary tube heat exchanger, a copper tube heat exchanger, a plate heat exchanger, or the like. Preferably, the heat exchanger is arranged at least on side walls, preferably also on the rear wall and optionally on the ceiling of the receiving area. The rigid connection between the receiving area and the second insulating element is retained. For this purpose, the distance between tubes of the heat exchanger is dimensioned sufficiently large. The distance between outer sides of the tubes is at least the diameter of the individual tubes. To complete emptying of the To allow heat exchanger, the tubes of the same can be mounted vertically or at least obliquely with sufficient slope at the receiving portion.
Gemäß einer weiteren Ausführungsform ist der Wärmetauscher in berührendem Kontakt mit dem Aufnahmebereich.According to a further embodiment, the heat exchanger is in touching contact with the receiving area.
Beispielsweise kann der Wärmetauscher in linienförmigem Kontakt mit dem Aufnahmebereich sein. Alternativ können die Rohre des Wärmetauschers beispielsweise eine rechteckige Geometrie aufweisen, wodurch eine größere Kontaktfläche mit dem Aufnahmebereich erzielt wird. Optional kann zur Verbesserung der thermischen Anbindung des Wärmetauschers an den Aufnahmebereich ein Material mit guter Wärmeleitfähigkeit verwendet werden. Hierzu kann beispielsweise eine Wärmeleitpaste Anwendung finden. Diese Wärmeleitpaste passt sich gut an die Kontur des Wärmetauschers und an die Oberfläche des Aufnahmebereichs an. Vorzugsweise weist die Wärmeleitpaste eine spezifische Wärmeleitfähigkeit von 0,5 W/(m*K) oder größer auf. Die Wärmeleitpaste wird vorzugsweise nur in dem Bereich des Wärmetauschers auf den Aufnahmebereich aufgetragen.For example, the heat exchanger may be in linear contact with the receiving area. Alternatively, the tubes of the heat exchanger, for example, have a rectangular geometry, whereby a larger contact surface is achieved with the receiving area. Optionally, to improve the thermal connection of the heat exchanger to the receiving area, a material with good thermal conductivity can be used. For this purpose, for example, find a thermal paste application. This thermal compound adapts well to the contour of the heat exchanger and to the surface of the receiving area. Preferably, the thermal paste has a specific thermal conductivity of 0.5 W / (m * K) or greater. The thermal compound is preferably applied to the receiving area only in the region of the heat exchanger.
Gemäß einer weiteren praktischen Ausführungsform ist eine Auftrennung der adhäsiven Verbindung zwischen dem ersten Isolationselement und dem zweiten Isolationselement beziehungsweise dem Masseelement in akustischer Hinsicht von Vorteil. Die Auftrennung kann durch Verwendung einer Trennschicht, wie beispielsweise einer Wachsschicht oder ähnlichem oder einer Polyethylen-Folie erfolgen. Die Trennschicht weist vorzugsweise eine freie Oberflächenenergie größer 25 mN/m, bevorzugt größer 35 mN/m, auf.According to a further practical embodiment, a separation of the adhesive connection between the first insulation element and the second insulation element or the mass element is acoustically advantageous. The separation can be done by using a release layer such as a wax layer or the like or a polyethylene film. The separating layer preferably has a surface free energy of greater than 25 mN / m, preferably greater than 35 mN / m.
Die Verbindung des ersten Isolationselements mit dem Aufnahmebereich kann überdies adhäsiv erfolgen; dies ist aber keine zwingende Voraussetzung. Auf jeden Fall ist darauf zu achten, dass der Raum zwischen dem Aufnahmebereich und dem zweiten Isolationselement weitestgehend mit dem ersten Isolationselement ausgefüllt ist, so dass eine Kraftübertragung senkrecht zu dessen Oberfläche möglich ist. Diese ist bei vollständiger Füllung auch ohne adhäsive Verbindung möglich. Dadurch wird eine Reduktion der abgestrahlten Schallleistung erzielt. Diese Kraftübertragung kann auch dann erfolgen, wenn das erste Isolationselement nur teilweise an dem Aufnahmebereich oder dem zweiten Isolationselement anliegt.Moreover, the connection of the first insulating element to the receiving area can take place adhesively; but this is not a mandatory requirement. In any case, care should be taken that the space between the receiving area and the second insulating element is largely filled with the first insulating element, so that a force transmission perpendicular to the surface is possible. This is possible with complete filling without adhesive connection. This achieves a reduction of the radiated sound power. This power transmission can also take place when the first insulating element rests only partially on the receiving area or the second insulating element.
Weiterhin sollte die Verbindung zwischen dem zweiten Isolationselement und dem Abdeckelement adhäsiv sein; dies ist aber keine zwingende Voraussetzung.
Auch kann der Einsatz von viskoelastischem Polyurethan-Schaum akustisch vorteilhaft sein. Dadurch können akustische Schwingungen bereits in dem ersten Isolationselement gedämpft werden. Der Verlustfaktor des ersten Isolationselements sollte somit größer als 0,01, bevorzugt größer als 0,1, sein.
Weiterhin wird ein Aufnahmebereich für ein wasserführendes Haushaltsgerät, insbesondere ein Spülbehälter für eine Geschirrspülmaschine, mit einer derartigen Anordnung vorgeschlagen.
Der Spülbehälter ist vorzugsweise aus einem Stahlblech gefertigt.Furthermore, the connection between the second insulating member and the cover should be adhesive; but this is not a mandatory requirement.
The use of viscoelastic polyurethane foam may also be acoustically advantageous. As a result, acoustic vibrations can already be damped in the first insulating element. The loss factor of the first insulating element should thus be greater than 0.01, preferably greater than 0.1.
Furthermore, a receiving area for a water-conducting household appliance, in particular a washing container for a dishwasher, proposed with such an arrangement.
The washing container is preferably made of a steel sheet.
Mit der erfindungsgemäßen Anordnung lässt sich beispielsweise in dem Bereich einer Tür einer Geschirrspülmaschine eine Reduktion der Schallemission von zirka -1 dB(A) rel. 1 pW und eine Reduktion der Energieaufnahme von bis zirka -40 Wh erreichen.
Das wasserführende Haushaltsgerät kann auch eine Waschmaschine sein. Alternativ kann die Anordnung auch bei anderen wasserführenden Haushaltsgeräten eingesetzt werden.With the arrangement according to the invention, for example, in the area of a door of a dishwasher, a reduction of the acoustic emission of approximately -1 dB (A) rel. 1 pW and a reduction in energy consumption of up to about -40 Wh.
The water-bearing household appliance can also be a washing machine. Alternatively, the arrangement can also be used in other water-conducting household appliances.
Weitere vorteilhafte Ausgestaltungen und Aspekte des wasserführenden Haushaltsgeräts mit einem Aufnahmebereich sind Gegenstand der Unteransprüche.

Das Haushaltsgerät 1 weist weiterhin zumindest eine Spülgutaufnahme 12 auf. Insbesondere können mehrere Spülgutaufnahmen 12 vorgesehen sein, wobei jeweils eine der mehreren Spülgutaufnahmen 12 ein Unterkorb, ein Oberkorb oder eine Besteckschublade des Haushaltsgeräts 1 ist. Die mehreren Spülgutaufnahmen 12 sind vorzugsweise übereinander in dem Aufnahmebereich 2 angeordnet. Jede Spülgutaufnahme 12 ist wahlweise in den Aufnahmebereich 2 hinein oder aus diesem heraus verlagerbar. Insbesondere ist jede Spülgutaufnahme 12 in einer Einschubrichtung E (Pfeil) in den Aufnahmebereich 2 hineinschiebbar und entgegen der Einschubrichtung E (Pfeil) in einer Auszugsrichtung A (Pfeil) aus dem Aufnahmebereich 2 herausziehbar.The

Das erste Isolationselement 14 weist eine Dicke d14 von bevorzugt 5 bis 50 mm, weiter bevorzugt von 10 bis 45 mm, weiter bevorzugt von 15 bis 40 mm, weiter bevorzugt von 20 bis 35 mm, weiter bevorzugt von 25 bis 30 mm, auf. Eine Dichte ρ14 des ersten Isolationselements 14 beträgt zwischen 5 und 90 kg/m3. Eine spezifische Wärmeleitfähigkeit λ14 des ersten Isolationselements 14 ist vorzugsweise kleiner als 0,1 W/(m*K), bevorzugt kleiner als 0,05 W/(m*K). Das erste Isolationselement 14 weist weiterhin vorzugsweise eine spezifische Wärmekapazität c14 von weniger als 1.400 J/(kg*K) auf.The
Die Anordnung 13 kann an der gesamten Wandung 6 des Aufnahmebereichs 2 vorgesehen sein. Insbesondere kann die Anordnung 13 an den Seitenwänden 10, 11, der Rückwand 9, der Decke 8 und dem Boden 7 vorgesehen sein. Weiterhin kann die Anordnung 13 auch an der Tür 3 vorgesehen sein. Alternativ kann die Anordnung 13 auch nur an den Seitenwänden 10, 11 und beispielsweise an der Rückwand 9 und/oder der Decke 8 vorgesehen sein. Im Folgenden wird zur Vereinfachung nur auf die Seitenwand 11 Bezug genommen.The
Das erste Isolationselement 14 ist direkt an den Aufnahmebereich 2, insbesondere direkt an die Wandung 6, angeschäumt. Hierzu können dem Material des ersten Isolationselements 14 chemische Zusätze beigemischt werden, die ein Lösen des ersten Isolationselements 14 von der Wandung 6 verhindern. Weiterhin kann die Außenfläche 15 der Seitenwand 11 alternativ oder zusätzlich vorbehandelt, beispielsweise aufgeraut werden, so dass sich die Verbindung zwischen der Seitenwand 11 und dem ersten Isolationselement 14 nicht löst. Durch das vollflächige Aufbringen des ersten Isolationselements 14 auf die Wandung 6 wird eine gute thermische Isolation des Aufnahmebereichs 2 sichergestellt. Ein weiterer Vorteil bei der kompletten Umschäumung des Aufnahmebereichs 2 mit dem ersten Isolationselement 14 ist, dass vorhandene Spalte lückenlos abgeschlossen werden, wodurch auch eine verbesserte akustische Isolation gewährleistet ist.The
Die Anordnung 13 weist weiterhin ein zweites Isolationselement 16 auf. Das zweite Isolationselement 16 ist auf dem ersten Isolationselement 14 angeordnet, so dass das erste Isolationselement 14 zwischen dem Aufnahmebereich 2 und dem zweiten Isolationselement 16 angeordnet ist. Beispielsweise kann das erste Isolationselement 14 an den Aufnahmebereich 2 angeschäumt werden und anschließend das zweite Isolationselement 16 an dem ersten Isolationselement 14 angebracht werden. Alternativ kann das erste Isolationselement 14 zwischen den Aufnahmebereich 2 und das zweite Isolationselement 16 direkt eingeschäumt werden. Das erste Isolationselement 14 ist vorzugsweise direkt mit dem zweiten Isolationselement 16 verbunden. Hierzu können dem Material des ersten Isolationselements 14, wie zuvor erläutert, entsprechende chemische Zusätze beigemischt werden, die eine zuverlässige und dauerhafte Verbindung mit dem zweiten Isolationselement 16 gewährleisten. Alternativ oder zusätzlich kann eine Oberfläche 17 des zweiten Isolationselements 16, die in Richtung des Aufnahmebereichs 2 weist, oberflächenbehandelt, beispielsweise aufgeraut sein, um eine sichere und dauerhafte Verbindung des ersten Isolationselements 14 mit dem zweiten Isolationselement 16 zu gewährleisten.The
Eine Dicke d16 des zweiten Isolationselements 16 ist vorzugsweise geringer als die Dicke d14 des ersten Isolationselements 14. Beispielsweise kann die Dicke d16 1 bis 10 mm, bevorzugt 1 bis 8 mm, weiter bevorzugt 1 bis 5 mm, weiter bevorzugt 1 bis 3 mm, betragen. Das erste Isolationselement 14 bewirkt eine steife Verbindung des zweiten Isolationselements 16 mit dem Aufnahmebereich 2. Insbesondere ist das erste Isolationselement 14 dazu eingerichtet, Schwingungen von dem Aufnahmebereich 2 auf das zweite Isolationselement 16 zu übertragen. Das erste Isolationselement 14 ist vorzugsweise nicht dazu eingerichtet, Schwingungen zu dämpfen. Insbesondere verhindert das erste Isolationselement 14 eine Wärmeübertragung von dem Aufnahmebereich 2 auf das zweite Isolationselement 16. Hierdurch kann das zweite Isolationselements 16 dem Aufnahmebereich 2 keine Wärme entziehen. Dadurch wird die Energieeffizienz des Haushaltsgeräts 1 verbessert. In dem zweiten Isolationselement 16 werden Schwingungen des Aufnahmebereichs 2 in Wärme umgewandelt.A thickness d 16 of the second insulating
Das zweite Isolationselement 16 weist vorzugsweise eine deutlich höhere Dichte als das erste Isolationselement 14 auf. Das zweite Isolationselement 16 ist vorzugsweise aus einem Bitumenmaterial, insbesondere aus einem metall- und/oder gesteinsgefüllten Bitumenmaterial, oder aus einem Kunststoffmaterial, insbesondere aus einem metall- und/oder gesteinsgefüllten Kunststoffmaterial gefertigt. Beispielsweise kann das zweite Isolationselement 16 aus einem Butylmaterial gefertigt sein. Das zweite Isolationselement 16 ist insbesondere platten- oder mattenförmig. Das zweite Isolationselement 16 kann auch ein Metallblech, insbesondere ein Stahlblech, sein.
Das zweite Isolationselement 16 dient der Entdröhnung des Aufnahmebereichs 2 beziehungsweise der Dämpfung von Schwingungen des Aufnahmebereichs 2. Das zweite Isolationselement 16 weist vorzugsweise einen möglichst hohen Verlustfaktor auf. Unter einem Verlustfaktor ist vorliegend bei physikalischen Schwingungen unterschiedlicher Natur das Verhältnis des verlustbehafteten Realteils zum verlustfreien Imaginärteil einer komplexen Größe zu verstehen. Der Verlustfaktor des Materials des zweiten Isolationselements 16 ist bei 20 °C größer als 0,08, bevorzugt größer als 0,15. Eine Dichte ρ16 des zweiten Isolationselements 16 ist vorzugsweise größer als 1.000 kg/m3.
Die Anordnung 13 weist weiterhin ein in der
Vergleich zu einem idealen Wärmestrahler, einem schwarzen Körper, abgibt. Vorzugsweise weist das Abdeckelement 18 einen Emissionskoeffizienten von kleiner als 0,5, bevorzugt von kleiner als 0,1 auf. Hierdurch kann der Energieverlust weiter reduziert werden. Vorzugsweise kommt als Material für das Abdeckelement 18 Aluminiumfolie zur Anwendung.The

Weiterhin können die Rohre 22 bis 25 mit Hilfe einer Wärmeleitpaste 26 thermisch mit der Seitenwand 11 gekoppelt sein. Mit Hilfe des Wärmetauschers 21 ist eine Wandtemperatur des Aufnahmebereichs 2 steuerbar. Hierdurch kann ein gutes und reproduzierbares Trocknungsergebnis erreicht werden. Der Wärmetauscher 21 kann beispielsweise als Kapillarrohrwärmetauscher, Kupferrohrwärmetauscher, Plattenwärmetauscher oder dergleichen ausgebildet sein. Vorzugsweise ist der Wärmetauscher 21 an mindestens einer Seitenwand 10, 11, vorzugsweise an beiden Seitenwänden 10, 11, an der Rückwand 9 und optional an der Decke 8 des Aufnahmebereichs 2 vorgesehen. Zur Verbesserung der natürlichen Konvektion ist der Wärmetauscher 21 vorzugsweise an senkrechten Flächen des Aufnahmebereichs 2 vorgesehen. Die steife Verbindung zwischen dem Aufnahmebereich 2 und dem zweiten Isolationselement 16 mit Hilfe des ersten Isolationselements 14 wird dabei aufrechterhalten. Hierzu wird ein Abstand a21 zwischen jeweils zwei Rohren 22 bis 25 des Wärmetauschers 21 so gewählt, dass ein ausreichender Kontakt des ersten Isolationselements 14 mit dem Aufnahmebereich 2 gewährleistet ist. Der Abstand a21 entspricht vorzugsweise mindestens einem Durchmesser d21 der einzelnen Rohre 22 bis 25. Dies entspricht bei einem Rohrdurchmesser d21 von kleiner als 10 mm beziehungsweise von kleiner als 5 mm einem Abstand a21 von mindestens 10 mm beziehungsweise mindestens 5 mm.Furthermore, the
Die Wärmeleitpaste 26 passt sich gut an die Kontur des Wärmetauschers 21 und an die Oberfläche des Aufnahmebereichs 2 an. Hierdurch ist eine gute Wärmeübertragung gewährleistet. Vorzugsweise weist die Wärmeleitpaste 26 eine spezifische Wärmeleitfähigkeit λ26 von 0,5 W/(m*K) oder mehr auf. Die Wärmeleitpaste 26 wird nur in dem Bereich des Wärmetauschers 21 auf den Aufnahmebereich 2 aufgetragen. Alternativ oder zusätzlich kann die Geometrie des Wärmetauschers 21 konstruktiv an die Oberfläche der Seitenwand 11 angepasst werden. Beispielsweise können die Rohre 22 bis 25 rechteckförmig oder halbkreisförmig ausgebildet sein. Um eine vollständige Entleerung des Wärmetauschers 21 zu ermöglichen, können die Rohre 22 bis 25 senkrecht oder zumindest schräg mit ausreichendem Gefälle angebracht werden.The

Das zweite Isolationselement 16 kann beispielsweise als Matte oder Platte auf das erste Isolationselement 14 aufgelegt werden. Alternativ kann das erste Isolationselement 14 zwischen den Aufnahmebereich 2 und das zweite Isolationselement 16 eingeschäumt werden, so dass das erste Isolationselement 14 direkt mit dem Aufnahmebereich 2 und dem zweiten Isolationselement 16 verbunden wird. Das Anordnen des zweiten Isolationselements 16 an dem Aufnahmebereich 2 kann vor oder nach dem Anschäumen des ersten Isolationselements 14 erfolgen.The
Die thermische Isolation des Aufnahmebereichs 2 mittels des ersten Isolationselements 14 verhindert über den gesamten Spülzyklus weg eine Wärmeübertragung in die akustisch wirksamen Materialien, das heißt in das zweite Isolationselement 16 und in das optionale Masseelement 20. Das zweite Isolationselement 16 und das Masseelement 20 können so auf dem Temperaturniveau der Umgebung gehalten werden. Dies hat zur Folge, dass wenig bis keine Energie aufgewandt werden muss, um diese aufzuheizen. Durch den Einsatz eines effizienten Wärmetauschers 21 wird ferner ein gutes und reproduzierbares Trocknungsergebnis gesichert.The thermal insulation of the receiving
